The main objects of this invention are, to provide an improved form of reading lamp for use with those types of furniture wherein the support for the body comprises hinged sections relatively adjustable for disposing the .body of the occupant in various angular positions between the horizontal and vertical; to provide an improved form of mounting for a lamp of this kind which synchronizes an angular adjustment ofthe lamp with respect to the body support with. any angm' lar adjustment of said bodysupport so that the lamp is always at the best possible positiongfor illuminating any printed matter the occupant may want to read; and to provide an improved lamp, mounting, and shifting means of this kind which is very simple in construction, facile to attach. to the furniture, and positive in operation.

In the accompanying drawings:

The figure indicates in full, dotted,;and dot-and-dash outlines various angular positions which the lamp post automatically assumes when the bed-bottom section, whereon the lamp is mounted, is shifted into positions above and below the normal horizontal position;

A lamp construction 5 embodying this invention comprises a post or arm 8, abracket 'l, and an operating link 8. As will be pointed out pres ently, these parts are provided with means for convenient mounting of the lamp Bfon a bed 9, comprising a supporting frame or element it and a multiple bed-bottom section H. The arrange ment is such that the lamp 5 will be disposed in the angular position best suited for reading purposes by the occupant of the bed for; any position to which the adjustable bed-bottom sections may be shifted.

The lamp post 5 as herein shown is of tubular form. The upper end 12 is bent at an angle to provide a support for a lamp l3. U-shaped blocks M and 15 are rigidly secured to the post 5 near the lower end thereof in spaced longia lamp, with its mounting and operating parta'constructed in ac-.

The bracket 7 is pivoted at It to the block I, and at its outer end mounts a clamp H by 5 means of which the bracket is rigidly secured: to

theside rail of one of the sections of the bed bottom H. As clearly shown in the figures, the clamp I1 is a piece of metal in substantially the form of a V, having one leg thereof brazed or otherwise secured to the bracket 1 and supporting a threaded clamping pin l8fon the other leg. A pair of pins l9 are secured to the bracket 1 on opposite sides of the clamp I! so as to coact with the clamping pin Hi to secure the bracket rigidly in place on one of the bed-bottom sec-v tions II, as will appear. more fully hereinafter. Intermediate its ends the bracket 1 is bent to slightly offset inwardly the end which supports the clamp ll from the end attached to the block [4. This serves to space the lamp post 6 out from the side rail of the bed bottom ll, asshown in Fig.4. The operating link 8 is in the form of a rod hinged at 2!! "to the block 15 and formedatth opposite end 2| with angular offset adaptedtobe received in and extend through an aperture in a part of the bed frame In, aswill be pointed out directly. 7 g The lamp l3, as herein shown,is preferablyof the fluorescent type having a conventional bulb 22 mounted in a canopy 23. .The usual lamp sockets are connected by an'electric conduit 2.4, extending through the tubular lamp post 6, to a suitable plug 25.

The bed 9 wherewith this improved'lamp has been particularly designed is of thetype shown in co-pending application Serial No'. 741,870,,filed April 16,1947. Its use of course is by'no means limited to that type of bed. Such a bed has the frame or element It supported in the usual manner by a bedstead head 26 and a companion bed? stead foot (not shown). A plate or bracket 21 secured to the frame 10 provides a pivotal mountbottorn ll. As herein H comprises a back section Ila and a seat section Ilb hinged together at 28 with the former hingedly supported. at 29. on the plate or bracket 21. These bed-bottom sections Ha and III are formed of the usual angle-iron material, with a wire fabric for supporting amattress. V. T Near the; head end, one of the ed er-1310mm back section Ila (preferably at the left-hand side of the bed as viewed from the occupants position on the bed.) has formed therein, in the verti orally-disposed flange thereof, a pair of apertures 30. These are positioned so as to receive the pins (9 on the lamp post bracket 7, thereby co-acting with the threaded clamping pin l8 to rigidly secure the bracket 1 to the bed-bottom section 1 la.

The plate or bracket 27 has an aperture 3! formed therein to receive the bent-over end 2| of the operating link 8.- As shown in Fig. 2 this aperture is placed near the upper end of the plate 21. It must be in such a position that as the bed-bottom section Ha shifts on its pivot 29 the link 8 will effect the desired alteration in the angular disposition of the lamp post 6 relative to the bed-bottom section I la.

As clearly appears from Fig. 2,. the. bed bottom section Ha may be shifted either below or above a normal horizontal position. Although the angularity of the lamp post 6- with respect to the bed-bottom section Ila will not be altered materially when the bed-bottom H is shifted to an inclined position below horizontal, it is apparent from this view that the angularity of the lamp post 6 with regard to the bed-bottom section 'tl'a is materially increased as the bed-bottom section Ha is shifted toward an u'priglit'position. t is when the bed-bottom section [la is shifted toward a vertical position that the altered angularity of the lamp post with respect to the bed-bottom section Ha is most important. The more nearly the bed-bottom section I la approaches the vertical position the more the lamp it needs to be shifted he'adwardly of the bed away from the head of the occupant lying on the bed-bottom section Ila. Such a headwardly shifting of the lamp i3 is needed to provide better illumination for any reading the occupant on the bed-bottom section l'lctmay want to do.

It will be obvious from the foregoing that any bed or chair with an adjustable body-supporting? section provided with apertures 30 and 31 will accommodate a lamp construction embodying this invention.

Qther variations and modifications in the details of structure 'and arrangement of the parts may be resorted to within the spirit and coverage of the appended claims.
